SPECIFICATION forming part of Letters Patent No. 650,713, dated May' 29, 1,900.

- Application filed Septernher, 1899. Serial No. 729,424. (No model.)

To all whom it may concern: y

Be it known that I, WILLAM D. EVANS, a citizen of the United States, residing at Shela ton, county of Fairfield, State of Connecticut, have invented a new and useful Quadruple Strop, of which the following is a specification.

My invention relates to the class of strops for general use in which two independent strips of leather' or of canvas or a strip of leather and a strip of canvasare placed face to face and one or both ends secured together.

My present invention has for its object to provide a simple and inexpensive flexible quadruple strop-z'. e., a strop consisting of two independent strips of leather or canvas or a strip of leather and a strip of canvas, both faces of both strips being finished with operative surfaces and said strips being so connected together that either face of either strip may be instantly placed uppermost, so as to be in position for use.

With these ends in view I have devisedthe novel quadruple flexible strop which I will now describe, referring by numbers and letters to the accompanying drawings, forming part of this specification, in which- Figure 1 is an edge view of my novel quadruple strop, one of the strips being shown in one position in full lines and in the' reverse position in dotted lines; Fig. 2, a face view showing one of the operativesurfaces in position for use, and Fig. 3 is a view illustrating the Way in which the strop is manipulated in order to transpose the inner and the outer faces.

A and B denote the strips, either orboth of which may be of leather or of canvas.V

Each side of each strip is provided withv an operative surface, each surface in practice of course differing from all of the other surfaces. The operative surfaces of strip A are indicated by 10 and 11, and the operative surfaces of strip B are indicated by 12 and 13. These strips are so hinged .together as to enable them to be transposed-Li'. e., reversed-e so that the inner or inoperative surfaces may be placed in operative position and the previously-operative surfaces be placed upon the inner side an'd out of operative position. In the present instance I have shown one end of each strip as secured by rivets or eyelets 2O to an independent hinge-plate, which may be made of metal, leather, or any suitable material. lf preferred, the hinges may be formed from the material of the strips themselves'. In the drawings the hinge-plate of strip A is indicated by C and the hinge-plate of strip B by D. Hinge-plate C is provided with two knuckles 14, having between them a recess 15, and hinge-plate D is provided with a knuckle 1G, which is adapted to lie between knuckles let and is cut away on opposite sides of knuckle 16, leaving recesses 17.

1S denotes a pintle which passes through knuckles la and 16.

19 denotes a swivel, preferably ringed, as shown in the drawings, which turns in the outer edge of knuckle 16 and is adapted to pass freely through recess 15 in hinge-plate C when the hinge-plates are reversed.

The special construction of the hinge-plates and the knuckles and their mode of attachment to the strips is of course not of the essence of my invention. I have shown the two hinge-plates as made double, the piece of metal, leather, or other material from which each plate is formed being bent upon itself and having a knuckle-or knuckles formed at its mid-length and the two ends of the hinge plate receiving the end of the strip between them.

Invuse the operator engages the swivel with a suitable support, as a hook, nail, or other projection, (not shown in the drawings,) and taking hold of the strips by their free ends holds them face to face in position for use. In practice the free ends of the strips, if made of leather, are suitably shaped to form convenient handles, and if made of canvas are provided with leather handles. The free ends of the strips, however, have not been shown in the drawings, as the use or non-use of any special form of 'handles is not of the essence of my invention;

In Fig. 2 the strop is in operative position, surface 10 being uppermost and in position for use. In case it should be required to use surface 13 the operator would simply turn the strop on the swivel without detaching the latter from the support. Should it be desired, however, to use either surfaces 11 or 12, the operator would detach the swivel from Ico the support and turn the knuckle or knuckles of one hinge-plate on the pintle, the swivel passing through recess 15, as in Fig. 3, thereby transposing the inner and the outer surfacesthat is, making surfaces 11 and 12 the outer surfaces and surfaces 10 and 13 the inner surfaces, which is the reverse of the position in which said surfaces are shown in Fig. 1. Having transposed the surfaces as just described, the operator again engages the swivel with the support and places either surfacell or 12 uppermost in position for use as may be required.

Having thus described my invention, I claim-f l. In a strop the combination with two ilexible strips finished on both sides, of reversible hinge -plates to which said strips are attached so that either side of either strip may be placed in operative position.

2. In a strop the combination with two ilexible strips, of hinge-plates to which said strips are respectively attached, one of said hingeplates having two knuckles with a recess between them and the other hinge-plate having a central knuckle adapted to lie between the other knuckles and provided with a swivel adapted to pass through the recess so that th strips may be transposed.

In testimony whereof I allix my signature in presenceof two witnesses.
